Our Stake uses the same lesson schedule for the Melchizedek Priesthood and Relief Society. Instead of having to enter the same schedule 3 times, could a feature be added to assign the same schedule to more than one organization?

See this thread and this thread as well as some others I am too lazy to hunt down. The developers are aware of the need and requests for this type of suggestion. Just make sure you submit your suggestion using the feedback link on LDS.org.
